What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change of brain volume before and after treatment
Time Frame: before operation; 3-10 Days after operation; 1 month; 6-12months
The change of brain volume (mm3) are evaluated by structural 3DT1 weighted MRI. Freesurfer software is used to get the measured value of the volume.
before operation; 3-10 Days after operation; 1 month; 6-12months
Change of cerebrovascular morphology before and after treatment
Time Frame: before operation; 3-10 Days after operation; 1 month; 6-12months

Change of brain function connectivity before and after operation
Time Frame: before operation; 3-10 Days after operation; 1 month; 6-12months
The change of brain functional connectivity intensity are evaluated by rest stage functional MRI. DPABI software based on MATLAB is used to get the measured the matrix value of functional connectivity.

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
